Have you been experiencing the &quot;instantiate&quot; error message in your eventlog?

When a subscriber clicks on the subscribe button to sign up for newsletters via the subscribe panel, the subscriber is not taken to the Thank you page. Instead, the subscriber gets the message with the message: "Sorry, sending the email to request your confirmation failed, please click "Reload" to try again. If it still does not work, it may be because you are listed on our "Black List", which means that you cannot receive emails from our newsletter system. In that case, please contact the administrator."

The subscriber does appear in the users list and the mailing list member list but the subscriber cannot confirm the subscription request because do get an email requesting confirmation.

An effective way (IMO) to search both the forum and the bugtracker in one go, is using Google. In this case you might try this search string: site:phplist.com Mailer Error: Language string failed to load: instantiate

I've messed around with both /admin/class.phplistmailer.php and /admin/phpmailer/class.phpmailer.php and even got as far as fiddling with class.smtp.php to no avail... Trieds all the line 4/24/109 hacks, no nothing!

I'm not positive if there's a sendmail 'service' installed on my Apache though....
